Metric System

For the origin and underlying principles of the metric system consult any modern arithmetic (Milne's Standard, for example). The nurse should know the metric tables and the equivalents between the metric and common systems for measures of volume and weight. She does not require linear and square measure, nor measures of capacity except in a few instances.

The subjoined tables and equivalents will suffice.

Tables Measures Of Volume

In measuring small quantities the cubic centimeter is the unit.

1 cubic centimeter.......................= 1.0 cc.

10 cubic centimeters ...................... = 10.00 cc.

1 cubic millimeter ....................... = 0.1 cc.

1-100 cubic millimeter .....................

1-1000 cubic centimeter .....................

= 0.001 cc.

etc., etc.

Measures 0f Weight

In measures of weight the gram is the unit.

1 gram ................. 1. 0 gm.

1 decigram .............. 0. 1 gm.

1 centigram ............. 0. 01 gm.

1 milligram ............. 0. 001 gm.

Table Of Equivalents

Appended is a table of all the denominations of weights and measures, opposite which are placed the metric system, with corresponding equivalents in wine measure and avoirdupois weights:
